I have a modem and cannot get the Nomad 3
to make a connection. What do I do?
There are a number of reasons why the modem
may not be able to connect. Navigate to the Modem
Menu screen in the GUI.
1. If the display says "Modem not detected", then
power down the logger and remove the front
panel. Check that all cables to the modem are
connected and that the ribbon cable is securely
connected between the two PC boards.
2. If the display says "Modem disabled", this means
that the Nomad 3 does not have a modem setup
file installed. Use the Nomad 3 Toolbox to create
a setup file and import it to the Data Logger with
the USB flash drive.
3. Once a modem setup file is imported, you can
test modem functionality by selecting the Set
Time Test in the Modem Menu. If the display
says "Modem unplugged", check that the ribbon
cable is securely connected between the two
PC boards.
4. If after performing the Set Time Test it displays
"No Response":
•
i. Check that the ribbon cable is securely
connected between the two PC boards.
•
ii. Ensure that there is a SIM card and that it is
inserted and locked in the modem properly.
5. If the Set Time Test asks for a SIM PIN, enter the
PIN that is programmed on the SIM card or the
PIN assigned by the cell provider.
6. If the PIN is entered incorrectly three times in a
row, the SIM card will become locked and you
will need to enter the PUK code for that SIM card.
The PUK code is an 8-digit number found on
the credit card-sized SIM holder. Contact your
service provider if you do not have this code.
If the PUK is entered incorrectly 10 times in a row,
the SIM will become deactivated and will need to
be replaced.
7. If the Set Time Test shows "Signal ---" followed
by "No response", ensure that the antenna cable
is connected to the modem.
8. If the Set Time Test shows a low signal strength
(<50%) and the display shows "Test Failed", there
is insufficient cell signal strength at this location.
Relocate the antenna or consider replacing it
with a directional Yagi antenna.
9. If the Set Time Test shows a high signal strength
(>50%) and the display shows "Test Failed",
please check the following:
•
i. Ensure that the inserted SIM card has been
activated with the local cell provider.
•
ii. Using the Nomad 3 Toolbox, check that the
appropriate cell provider has been selected and/
or APN, username,
and password parameters are correct.
•
iii. Navigate back to the Main Menu on the
screen. If there is an "o" above the signal strength
bars at the top right of the window, then the
modem is currently roaming. Use the Nomad 3
Toolbox to enable roaming in the modem
setup file.
An alert is telling me that my voltage is
"Out of normal range." How do I fix this?
This alert indicates that there is a problem with the
wiring of one of the sensors or the power to the
unit is too low. Double-check your wiring and refer
to any wiring diagrams necessary. Check that your
solar panel is in the proper orientation for maximum
battery charging.
An alert is telling me that there is
a "Ground wiring error." How do I fix this?
A ground wiring error occurs when a GND port is
shorted to an EGND port on one of the sensors.
Check the wiring on all sensors to ensure that these
ports are not connected. It is also possible that there
is a wiring problem at the sensor. Check the shield
trace at the sensor for any incorrect wiring.
I lost my PIN and cannot access the
Nomad 3 from the screen! How can I get
a replacement PIN?
If you are your company's account manager
administrator, go to www.skyserve.net/nomad3/
reset to generate an override key. An override
key is a 6-digit, time-sensitive number. At the PIN
request screen on the Nomad, select the middle
hotkey button underneath the key symbol. Enter
the override key and you will be provided with
a replacement PIN. You will have the option to
keep this PIN, change it to a new PIN, or disable
it completely.
